Another beneficial effect of embodiment disclosed above is that vacuum glass does not have bleeding point.There is no the true of bleeding point Empty glass good appearance, surface are complete, and can deep processing degree it is higher.The vacuum glass of above-described embodiment can continue processing The specific glass such as doubling glass, pad pasting glass are made, different purposes needs are met.

Inventor is, it is known that getter is passivation in atmosphere, and the activation of getter refers to the side by vacuum heat Method makes getter show air drawing characteristics.In embodiment disclosed above, an important function of heating in vacuum is exactly to make air-breathing Agent is activated.

After inventor is, it is known that vacuum glass sealing completion comes out of the stove, then large area is carried out and/or prolonged to vacuum glass Heating can destroy the vacuum of vacuum glass, result even in vacuum glass because it is heated it is uneven produce excessive internal stress And burst.For the vacuum glass of embodiment disclosed above, getter 3 is activated in heating under vacuum step, therefore very After the completion of empty glass capsulation, without again to getter carry out evapotranspire/activation/unseal, need not especially reuse high-frequency heating, The modes such as infrared heating getter evapotranspire/activation/unseal, and then simplify processing step, reduce cost.Moreover, Embodiment disclosed above results in the higher vacuum glass of vacuum, and especially heat-proof quality and/or sound insulation property is preferable Vacuum glass.

Inventor is, it is known that vitreum and/or sealant (such as seal glass) may discharge gas when being heated.Implement In example 1~5, an effect of getter 3 can be, in the preparation process of vacuum glass, especially the vacuum of vacuum glass Heat in encapsulation process, absorb possibly into the gas in cavity (5), to keep the vacuum in cavity (5) up to standard, and then make The heat-proof quality and/or sound insulation property of vacuum glass are preferable.

Inventor is, it is known that vitreum and/or sealant (such as seal glass) (such as 1~50 year) are used for a long time During, a certain amount of gas may be discharged.Another effect of getter 3 can be, in the use of vacuum glass Cheng Zhong, constantly absorbs possibly into the gas in cavity (5), to keep the vacuum in cavity (5) up to standard, and then makes vacuum The durability of glass is higher.

The vacuum glass of embodiment disclosed above, getter is not to be placed into by bleeding point in vacuum glass, is inhaled The size of gas agent is not limited by bleeding point.The desired amount of getter can be placed according to the size of vacuum glass cavity, for example Place 1g/cm³Getter above.

Getter in the vacuum glass of embodiment disclosed above is nonevaporable getter (Non Evaporable Getters).Nonevaporable getter after being evaporated through high-frequency heating without using, not in vitreous surface formation metal film, to true The transparency influence of empty glass is small.The transparent region accounting for obtaining vacuum glass is higher

Finally it should be noted that：Above example is only to illustrate the technical solution of the utility model rather than it is limited System；Although the utility model is described in detail with reference to preferred embodiment, those of ordinary skill in the art should Understand：Still embodiment of the present utility model can be modified or some technical characteristics are equally replaced Change；Without departing from the spirit of technical solutions of the utility model, it all should cover in the claimed technical scheme of the utility model Among scope.
